WHY FLEXIBLE LC

Built for What Other Dimming Lenses Can’t Do

Photochromic Is Too Slow

Photochromic lenses are very slow and react to UV only. Our LC switches electrically in 30–200 ms, even behind a windshield.

Glass LC Is Rigid and Heavy

Glass cells are flat and 43–110 mil (1.1–2.8 mm) thick. Our film is 8–47 mil (0.2–1.2 mm) and curves to fit the frame.
